自我客体化的女性对身体线索的注意和记忆偏向

采用点探测任务和再认任务探讨高低自我客体化女性对积极身体词和消极身体词的注意和记忆偏向,探讨自我客体化女性的糟糕任务表现的内在机制。结果发现,高自我客体化女性对积极身体词存在注意脱离困难,对积极身体词的反应时显著快于低自我客体化女性。研究结果证实了自我客体化女性存在对身体线索的注意和记忆偏向,说明自我客体化使女性对身体相关信息分配了更多的认知资源,会妨碍任务表现。     

不同自我和谐水平青少年的认知加工偏向

为了探究不同自我和谐水平青少年的认知加工特点,44名被试先后进行自我相关词语的点-探测任务和词语的再认任务,结果发现:(1)高自我和谐水平的青少年对自我相关的积极词表现出注意优先,低自我和谐水平的青少年对自我相关的消极词表现出注意优先,但两者注意偏向无显著差异;(2)高自我和谐水平的青少年对自我相关的积极词的再认反应时显著短于低自我和谐水平青少年的,对积极词表现出了记忆偏向;低自我和谐水平的青少年对自我相关的消极词、中性词的再认反应时显著短于对积极词的反应时,对消极词、中性词表现出了记忆偏向。因此,不同自我和谐水平的青少年在认知加工的记忆阶段存在特质一致性。     

相貌负面身体自我女性对相貌词的注意偏向眼动的证据

采用改进的点探测范式并结合眼动技术, 以相貌词(积极和消极)为刺激材料, 实验中积极相貌词?中性词、消极相貌词?中性词、积极相貌词?消极相貌词以及中性词?中性词配对呈现, 考察了相貌负面身体自我女性对相貌词的注意偏向及其时间进程。眼动数据的结果发现, 在积极相貌词?中性词和消极相貌词?中性词条件下, 与控制组相比, 相貌负面身体自我女性的首视点更频繁地指向消极相貌词, 对消极相貌词探测速度更快, 并且首视点维持在此类词语上的时间更长, 但未发现总体的注视时间偏向; 与积极相貌相比较时, 相貌负面身体自我女性呈现与上述相同的结果, 此时的注意模式为警觉?脱离困难。此外, 相貌负面身体自我的女性还表现出对积极相貌词的减速探测偏向。行为证据进一步显示, 相貌负面身体自我女性对消极相貌词存在注意脱离困难。在积极相貌词?消极相貌词配对条件下, 相貌负面身体自我女性对消极相貌词也表现出注意脱离困难。以上结果表明, 相貌负面身体自我女性对消极相貌词表现出警觉?脱离困难的注意偏向。     

初中生自尊的认知加工偏向效应研究

探讨了初中生自尊的认知加工偏向效应。结果发现：高自尊初中生对积极词具有显著的注意偏向效应,低自尊初中生对积极词和消极词均不存在注意偏向效应;当对比图片为高兴－生气或高兴－中性表情时,高自尊初中生对高兴表情均存在显著的注意偏向效应,当对比图片为高兴－生气时,低自尊初中生对生气表情产生明显的注意偏向效应;高自尊组与低自尊组初中生分别对与自我有关的正向、负向形容词存在显著的记忆偏向效应。     

超重女性对食物信息加工的注意偏向和记忆偏向

采用与食物图片相关的点探测任务和学习—再认范式考察超重女性对不同热量食物信息的注意偏向和记忆偏向。结果发现：(1) 超重女性对高热量食物信息存在注意警觉—注意脱离困难模式,对低热量食物信息仅表现为注意回避模式。(2) 超重组女性对高热量食物信息的再认正确率显著高于正常体重组,而对低热量食物信息的再认成绩组间差异不显著。研究结果证实了超重女性对高热量食物信息投入更多的认知资源,存在注意偏向和记忆偏向。     

表达形式影响自我积极偏向的表现:来自P200的证据

该研究运用事件相关电位技术,采用肯定和否定的表达方式呈现自我参照任务,探讨不同表达方式对自我积极偏向效应的影响。实验一中,行为数据显示,自我积极偏向效应表现的并不完整;ERP数据显示,P200波幅的结果与行为数据结果相一致。实验二中,行为数据显示,自我积极偏向效应表现得完整;ERP数据显示,P200成分上并未产生任何实验效应。综合两个实验结果,证明了不同表达方式对自我积极偏向效应的表现存在影响。导致这种差异的根本原因可能在于两种表达方式造成的注意资源不同。     

特质自我控制对食物线索注意偏向的影响及干预：来自眼动的证据

采用眼动技术,以BMI指数处于正常范围的女性为被试,考察特质自我控制对食物线索注意偏向的影响以及注意偏向训练在改变注意偏向强度上的干预效果。结果发现,对于高热量食物线索,低特质自我控制水平女性表现出了更强的注意偏向;注意偏向训练有效降低了低特质自我控制水平女性对高热量食物线索注意偏向的强度。上述结果表明,特质自我控制影响个体对食物线索的注意偏向,注意偏向训练能有效改变个体对食物线索注意偏向的强度。     

防御性自尊大学生注意偏向对记忆偏向的影响

摘 要 为考查防御性自尊大学生注意偏向对记忆偏向的影响，本研究将被试分为训练组和控制组，训练组接受注意偏向训练，之后完成记忆任务。记忆任务中呈现中性和攻击性词汇，要求被试对词汇进行自由回忆。结果发现，控制组对攻击性信息存在着记忆偏向，而训练组对攻击性信息的记忆偏向消失。注意偏向训练可以即时性地改变防御性自尊大学生对攻击性信息的注意偏向，注意偏向可能是特质一致性记忆的原因之一。     

外显、内隐记忆中不同认知方式个体的社会定向

以中文双字词为实验材料,分别从两个层面探讨场依存个体与场独立个体对社会词或非社会词的记忆有无偏向。实验一采用双任务,分散注意学习条件,实验二引入加工分离程序(PDP)。研究结果表明:(1)在双任务分散注意学习条件下,场依存个体对非目标社会词存在记忆偏向。(2)在内隐记忆成绩上,场依存个体对社会词存在记忆偏向,场独立个体对非社会词存在记忆偏向。     

青年人和老年人加工情绪图片过程中的注意偏向:眼动研究

利用眼动追踪技术,考察了老年人与青年人加工情绪图片过程中的注意偏向及再认成绩。给被试同时呈现积极、中性及消极情绪图片,分为注意和记忆两部分任务。基于线性混合模型的分析发现,与青年人相比,老年人表现出对积极图片更大的注意偏向,且在随后的再认过程中对积极情绪图片的再认正确率更高。结果支持了社会情绪选择理论,说明中国老年人同样存在“积极效应”,情绪加工过程中能够通过选择偏爱的积极情绪信息来适应老化。     

积极情绪促进对积极刺激注意偏向：投入与抽离

一系列研究结果被认为反映了积极情绪促进投入注意至积极刺激的偏向。然而,由于所使用的范式不能分离对积极刺激的注意投入偏向和抽离偏向,这些研究结果也可能反映了积极情绪促进从积极刺激抽离注意更少的偏向。本研究采用音乐聆听和事件回忆唤起被试的积极或中性情绪,随后要求被试完成点探测范式的变式任务,通过中性-中性条件与一致条件的反应时之差测量投入偏向,以及不一致条件与中性-中性条件的反应时之差测量抽离偏向,探讨积极情绪究竟促进投入偏向,还是促进抽离偏向。结果表明：（1）相比中性组,积极情绪组并没有表现出更大的中性-中性条件和一致条件的反应时之差。这说明,积极情绪没有促进投入注意至积极刺激的偏向;（2）相比中性情绪组,积极情绪组的不一致条件与中性-中性条件的反应时之差更大。这说明,积极情绪促进从积极刺激抽离注意更少的偏向。由此,积极情绪并不促进投入注意至积极刺激的偏向,而是促进对积极刺激的抽离偏向。     

自我客体化影响认知表现的研究现状

自我客体化的女性会内化他人的评价,把自己当做物品一样来定义和评价自我,并习惯性地对自己的身体以及外貌进行监测,从而导致身体羞耻、焦虑、“心流”体验的减少及身体内部感知的迟钝,并进一步造成更多的不良后果。以往的研究多关注于自我客体化在女性心理健康上造成的影响,很少有研究关注于自我客体户对认知表现的影响。本文梳理了自我客体户与认知表现的相关研究,以及自我客体户对认知表现可能的作用机制。未来研究需要从多方面来丰富自我客体化的操纵方式,通过实验的方式来检验自我客体化对认知表现的作用机制,以及考察不同的认知表现,并关注自我客体化对认知表现的累积效应。     

Self-objectification and well-being in women's daily lives

Laboratory experiments and surveys show that self-objectification increases body shame, disrupts attention, and negatively predicts well-being. Using experience sampling methodology, the authors investigated self-objectification in the daily lives of 49 female college students. Building on the predictions of objectification theory, they examined associations between internalizing an observer's perspective on the self and psychological well-being, and examined the moderating roles of trait self-esteem and appearance-contingent self-worth. Within-person increases in self-objectification predicted decreased well-being, but this association was moderated by trait self-esteem and trait appearance-contingent self-worth; high self-esteem, highly appearance-contingent participants reported increased well-being when they self-objectified. Furthermore, perceived unattractiveness partially mediated the main effect and the three-way interaction: high self-esteem, highly contingent participants experienced smaller drops in well-being when they self-objectified, in part because they felt less unattractive. These results suggest that in daily life, some women receive a boost from self-objectification, although most women experience decreases in well-being when self-objectifying.     

Negativity bias in false memory: moderation by neuroticism after a delay

The negativity bias is the tendency for individuals to give greater weight, and often exhibit more rapid and extreme responses, to negative than positive information. Using the Deese-Roediger-McDermott illusory memory paradigm, the current study sought to examine how the negativity bias might affect both correct recognition for negative and positive words and false recognition for associated critical lures, as well as how trait neuroticism might moderate these effects. In two experiments, participants studied lists of words composed of semantic associates of an unpresented word (the critical lure). Half of the lists were comprised of positive words and half were comprised of negative words. As expected, individuals remembered negative list words better than positive list words, consistent with a negativity bias in correct recognition. When tested immediately (Experiment 1), individuals also exhibited greater false memory for negative versus positive critical lures. When tested after a 24-hr delay (Experiment 2), individuals higher in neuroticism maintained greater false memory for negative versus positive critical lures, but those lower in neuroticism showed no difference in false memory between negative and positive critical lures. Possible mechanisms and implications for mental health disorders are discussed.     

Longevity of attentional bias modification effects for food cues in overweight and obese individuals

Accumulating evidence shows that overweight individuals exhibit an attentional bias for food and that this bias can be modified. This study investigated the longevity of such modification effects. Using a dot probe paradigm, a community sample of overweight and obese women (N = 104) was trained to direct attention towards (‘attend’) or away from (‘avoid’) food pictures. Participants completed five weekly training sessions. Attentional bias was measured before and after training, at 24 h and one-week follow-up. To increase generalisability, at each of the post-training and follow-up assessments, participants were shown a mix of old and new food pictures. They also completed another implicit bias measure, i.e. a word stem task. Attentional bias for food increased in the ‘attend’ group and decreased in the ‘avoid’ group. These retraining effects were maintained at 24 h and one-week follow-up, and extended to new food pictures. Participants in the ‘avoid’ group also produced relatively fewer food words on the word stem task than those in the ‘attend’ group. Results are consistent with predictions of cognitive-motivational models that attentional biases are malleable. They further suggest that attentional bias modification, which targets the implicit processes that underlie the heightened food responsivity in overweight individuals, could help combat pathological (over)eating.     

害羞者对模糊情境信息的解释偏向

以模糊情境句子和形容词为刺激材料,分别采用文本材料范式和改编的词汇情境联接范式,对害羞者的延时解释和即时解释偏向特点进行探讨。结果发现：害羞者对模糊情境信息不仅缺乏积极的即时解释偏向特点,而且也缺乏积极的延时解释偏向特点;害羞者未表现出消极的即时和延时解释偏向特点。研究表明害羞者可能是社交焦虑的前期阶段,对害羞者的干预可以通过引导其积极的解释偏向的方式来实现。     

Mere Exposure: Gender Differences in the Negative Effects of Priming a State of Self-Objectification

Objectification theory (Fredrickson & Roberts, 1997) holds that American culture coaxes women to develop observers' views of their bodies. The present study was designed to test whether a state of self-objectification can be automatically activated by subtle exposure to objectifying words. A state of self-objectification or of bodily empowerment was primed by the use of a scrambled sentence task. Women's ratings of negative emotions were higher and their ratings of the appeal of physical sex lower when primed with self-objectification than when primed with body competence. Men's ratings were unaffected by the primes. The results of this study suggest that mere exposure to objectifying media can play a significant role in the initiation of a self-objectified state along with its attendant psychological consequences for women.
